Kelly Osbourne said, "Yes!" The E! Fashion Police star, 28, told Britain's Hello! magazine that she and her boyfriend of one year Matthew Mosshart are officially engaged.

He popped the question during a romantic vacation in Anguilla, they revealed.

"I knew she was 'The One' pretty early on," the groom-to-be said.

Osbourne added: "I've never felt this close to another human being, ever. People say we're co-dependent but we just want to be together all the time."

Mosshart and Osbourne met at Kate Moss' wedding in summer 2011.

"Matthew made the biggest sacrifice anyone's ever made for me, to move away from everything that he knew to be with me in LA," Osbourne gushed to the British magazine.

"Long-distance relationships often don't work out. We'd dated for a year and knew we wanted to be together," she said. "Matthew has broken down every one of my walls. There's nothing I wouldn't do in front of him."

According to the magazine, her engagement ring (above) was inspired by her rocker dad, Ozzy Osbourne.

"I designed it to look like an earring that my father wore," she explained. "I used to hold my finger up to his ear when I was little and say, 'I want a ring like that.' Now I have one!"
